Optimization of the performance of a heavy-duty natural gas active pre-chamber (PC) engine
was conducted using computational fluid dynamics (CFD) simulations. Seven different …

Ducted fuel injection is a strategy that can be used to enhance the fuel/charge-gas mixing
within the combustion chamber of a direct-injection compression-ignition engine. The …

Enhancing mixture preparation upstream of the premixed autoignition zone is a solution to
reduce soot emission formation in compression ignition engines. With this aim, in recent …

Ducted fuel injection (DFI) has been proposed as a strategy to enhance the fuel/charge gas
mixing within the combustion chamber of a direct-injection mixing-controlled compression …

Reducing the impacts of medium-and heavy-duty (MD/HD) ground transportation can be
enabled by fuel-engine combinations that use lower compression ignition liquid fuels and …

Abstract Ducted Fuel Injection (DFI) is a strategy still in development, which has proved to be
effective in reducing soot emissions in compression ignition engines. It works by driving the …

The spray mixing process can be improved via straight (ST) duct fuel injection, but there is a
risk of potential heat transfer loss due to prolonged spray tip penetration (STP) and spray …

Ducted fuel injection (DFI) is a technique to attenuate soot formation in compression ignition
engines relative to conventional diesel combustion (CDC). The concept is to inject fuel …

Ducted fuel injection (DFI) is a develo** technology for reducing in-cylinder soot formed
during mixing-controlled combustion in diesel compression ignition engines. Fuel injection …

Ducted fuel injection (DFI) has been shown to attenuate engine-out soot emissions from
diesel engines. The concept is to inject fuel through a small tube within the combustion …
